Exodus, Chapter 14, Verse 30-31
30 Thus the LORD saved Israel on that day from the power of Egypt. When Israel saw the Egyptians lying dead on the seashore 31 and saw the great power that the LORD had shown against Egypt, the people feared the LORD. They believed in the LORD and in Moses his servant.
The Hebrew’s after the crossing of the red sea and seeing Gods great power feared Him with human fear; but not Holy fear. There was no love towards God; only fear. God desires a spiritual union with us; therefore our belief must be mingled with great love and affection.
This is why later Israel would make the golden calf since their hearts were dead to God after 400 years in Egypt. What was it about Egypt that enslaved the Israelites even after they were freed by God? Egypt was rich, so rich that even the Israelites were as self-indulgent as the Egyptians. It meant a daily life of giving in to your desires and the brief enjoyments of this passing life. They only thought of satisfying themselves with no thought of He that Is. They made faint offerings to false gods to justify their behavior. Their minds became weak and confused. Their mistakes and sins robbed them of peace that only comes from doing the will of He that Is.
We only find peace and happiness when we are in union with God and doing His Holy will. We are created by God for eternal happiness with Him. Things cannot bring us happiness. Therefore we must think, speak and act every day the will of God: Living regularly in our lives the Shema Yisrael.
Hear, O Israel: The Lord our God, the Lord is one; and you shall love the Lord your God with all your Heart, and with all your soul, and with your entire mind, and with all your strength.
